Enum RetentionMode 

pub enum RetentionMode {
    Full,
    Bounded {
        keep_last: usize,
    },
    SnapshotAnchored,
}

How the supervisor prunes sealed run files.

The kernel records the choice in the manifest’s feature_flags; actual retention enforcement is performed by a separate supervisor process and is out of scope for the kernel boot path.

Variants

Full

Keep every sealed run; never reclaim.

Bounded

Keep at most keep_last sealed runs; the supervisor reclaims older files.

Fields

keep_last: usize

The number of sealed runs to retain.

SnapshotAnchored

Keep the manifest plus a snapshot anchor and the tail since the anchor; older entries reclaim once a newer anchor is durable.

Trait Implementations

impl Clone for RetentionMode

fn clone(&self) -> RetentionMode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for RetentionMode

impl Debug for RetentionMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for RetentionMode

fn default() -> RetentionMode

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for RetentionMode

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for RetentionMode

impl Hash for RetentionMode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for RetentionMode

fn eq(&self, other: &RetentionMode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for RetentionMode

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
